python bluetooth

To communicate with an HC-05 Bluetooth module using Python, you will need to use a Python library that can handle Bluetooth communication. One option is the PyBluez library, which can be installed using pip:

Pip install pybluez

Once you have PyBluez installed, you can use it to connect to the HC-05 module and send and receive data over Bluetooth. Here is an example of how to connect to the HC-05 and send a message: 

import bluetooth

# Set the MAC address of the HC-05

bd_addr = "XX:XX:XX:XX:XX:XX"

# Open a Bluetooth socket

sock = bluetooth.BluetoothSocket(bluetooth.RFCOMM)

# Connect to the HC-05

sock.connect((bd_addr, 1))

# Send a message to the HC-05

sock.send("Hello, HC-05!")

# Close the Bluetooth socket

sock.close()

Note that you will need to replace the MAC address ("XX:XX:XX:XX:XX:XX") with the actual MAC address of the HC-05 module. You can get the MAC address of the HC-05 by using the AT+ADDR command in a serial terminal program, as described in a previous answer.

You can also use the PyBluez library to receive data from the HC-05 by using the recv() method of the Bluetooth socket. For example:

import bluetooth

# Set the MAC address of the HC-05

bd_addr = "XX:XX:XX:XX:XX:XX"

# Open a Bluetooth socket

sock = bluetooth.BluetoothSocket(bluetooth.RFCOMM)

# Connect to the HC-05

sock.connect((bd_addr, 1))

# Receive data from the HC-05

data = sock.recv(1024)

# Print the received data

print(data)

# Close the Bluetooth socket

sock.close()
